Facebook along with Instagram and WhatsApp have been down for over five hours, and this is the longest downtime in their history. Services “fell” at about 18: 40 Moscow time, and still no reports about the causes of the accident and the approximate time of its elimination have been received from official sources.
The failure affected not only external but also internal Facebook systems. According to The Verge, employees are unable to use the corporate communications system, as well as internal sites and tools. Email in the company works only for internal email addresses, and employees cannot log into accounts using email accounts at all. Moreover, according to The New York Times, Facebook staff cannot physically get to their workplaces due to the fact that along with the social network, the security system, along with electronic passes, stopped working.
Also The Verge reports that to solve the problem, Facebook had to send engineers to its data centers throughout the United States. And this means that the problem is very serious, its elimination requires the presence of personnel, and the recovery can take quite a long time.
Most experts are inclined to the version that Facebook (along with Instagram and WhatsApp) suffered from a DNS failure, in particular due to the fact that, for some reason, records related to Facebook services were removed from the global routing tables. Cloudflare senior vice president Dane Knecht noted that Facebook’s border gateway protocol routes were simply “taken out of the Internet.”
This doesn’t sound like a hacker attack, however, experts say. The architecture of Facebook, Instagram, and WhatsApp is so different that a single hack would not have killed all three services in one fell swoop. Moreover, about 5 minutes before Facebook crashed, Cloudflare recorded a flurry of BGP route updates for Facebook, which looks more like a centralized (and, judging by the result, unsuccessful) router update. The result was the loss of connections between Facebook servers, and at the same time the suspension of their service in the DNS.
The Forbes publication quotes a comment by the creator of the usher2.club website, which tracks Roskomnadzor’s blocking, Philip Kulin. According to him, the failure looks as if the company’s network was simply turned off along with the main and auxiliary services. He noted that this could have happened both due to internal work and due to external interference. The situation can drag on for a long time. “ It looks like Facebook has built a centralized management of the network, and it was there that they made a mistake ,” Kulin said.
Instagram.com is currently throwing a 5xx server error and Facebook is just reporting that something went wrong. The problem also seems to be affecting Oculus services. Users can download games that they have already installed, but social functions or installing new games do not work.
Meanwhile, top managers of the social network are trying to reassure users. Andy Stone, head of communications at Facebook, tweeted: “ We know that some people have problems accessing our apps and products. We are working to get everything back to normal as soon as possible, and we apologize for any inconvenience . ” The company’s CTO, Mike Schroepfer added: “ We have network problems and the team is trying to debug and restore everything as quickly as possible “.
Since the fall, Mark Zuckerberg’s fortune has shrunk by almost $ 7 billion, and Facebook shares have fallen by almost 6%.
